8/2/2019 TMF500E-01 Compact Concentrator and GUI

1/2

TECHNICAL DESCRIPTION

TMF500-E is based on a 32Bit RISC technology and embeds a keyboard for theaccess to the setup menu and data entry, and a wide LCD display, a double serialcommunication port RS232 or RS485 3kVA insulated, double USB port, an Ethernetport 10/100Mbits, a 32MB internal memory and an integrated Web Server. The unit hasa great number of analog and digital I/O (up to 96), so it is the perfect instrument forremote monitoring, controls and data acquisition systems.

The unit has been designed to operate in an wide range of temperature (from - 30 to +70C) and with a very low current consumption (< 1W). It can be used in applicationswhere the citizen power network is not available and must be powered by solar panels,lithium battery packs or other power sources like wind generators.

The TMF500E is an ETS device (Easy to Install) thanks to the mechanical coupling toa DIN BAR, and it is easy to be programmed both in local or remote mode by adedicate web-page. The on board Embedded Linux operating system, can be used todevelop customized routines.

The TMF500E is a multipurpose intelligent device to manage meteorological stations (AWS

Automatic Weather Stations), tide gauges, ADCPs, current meters and other SCADA devices.

Each unit is composed of a microcomputer programmed to acquire, normalize and process in-

field data. Collected data can be displayed locally using the embedded GUI (LCD display +

keyboard). The unit can be connected to a local or remote Control Centre via TCP-IP using

the secure built-in FTP and an HTTP servers. Each unit has an unique IP to allow a multi

station data network. The CPU embeds a Linux operating system and can host user programs

in C-Language.

Best performances of the

TMF500-E can be obtained

using the Envirtech SCADA

software envHydro. The user

can manage, by a centralized

position, many sensors and

actuators everywhere located

in the world. On the right the

screenshots show a typical

application of envHydro and

many control units deployed

in field for dams remote

control.

When used to receive data

from Envirtech Buoys, Adcp

and weather stations the unit

can be programmed to

process collected data and to

show them on the local

display. The software

envHydro, running on a local

PC, can also be used to show

collected meteorological and

oceanographic data, as well

as sea waves spectra and

3D currents.

The outdoor configuration can

be used to collect data

coming from area not covered

by public networks, using

VHF or UHF communications

and relaying them on a

public network, like cabled

xDSL-ADSL, WAN or

Satellites.

APPLICATION NOTE

The TMF500-E concentrator in a

typical application. Data coming from

in-field instruments are collected and

after normalization and mathematical

processing, are stored in local

Memory card. The embedded

FTP/HTTP server can be queried by

external clients, via the TCP-IP port

using a radio modem or a GPRS/Edge

terminal. In the picture on the right a

licence free radio modem is used to

transmit data to a control center.
